   Ship tends to be wet forward

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 90,5 %
      - Above water (accommodation/working, high = better): 135,3 %
   Waterplane Area: 54.847 Square feet or 5.095 Square metres
   Displacement factor (Displacement / loading): 99 %
   Structure weight / hull surface area: 198 lbs/sq ft or 967 Kg/sq metre

You have no reason for the deck to be 6''. Reduce it to 4.5'' and use the weight saved on the belt and reducing weight.

The deck isn't 6" per se, if he's using his 'normal' deck layout. 2" weatherdeck meeting at top of upper belt, 3" main armored deck meeting at top of main belt, 1" splinter deck at bottom of main belt/over machinery-magazine spaces. I think..or something similar. Basically OTL 'burster' deck armor plan.
